Ok. I have some thoghts on a proper fix which you may want to include
in the bug report. The problem is in two parts (or may be anyway, I
haven't actually looked at libc to verify this). First, applications
(such as tar) which expect lchown behaviour should call lchown and not
chown (tar call chown as it is now). Second, libc needs to figure out
if the particular kernel has a lchown syscall or not and divert calls
to lchown to the appropriate syscall.

AFAIK, yes. Just make sure to state that the bug is in the alpha
version of the package.
